TOOL HOLDER.

Application filed November 19, 1921 Serial No. 516,413. Renewed February 18, 1924.

17 0 all whom it may concern:

Be it known that I, KARL STUDINKA, a citizen of the United States, residing at Donors, in the county of Washington and 5 State of Pennsylvania, have invented new and useful Improvements in Tool Holders, of which the following is a specification.

This invention relates to holding devices, and more particularly to a tool holder for use in connection with lathes and similar machines.

One of the main objects of the invention is to provide a holder which will accommodate tools of different lengths.

A further object is to provide simple and efficient means for bracing the tool, Further ob ects will appear from the detailed description.

In the drawings Fi ure 1 is a side view of the holder; F1; ire 2 is a top plan vlew; Figure 3 18 a front view;

Figure 4 is a section taken substantially on line '-L-4E of Figure 2.

The holder includes a body 1 provided at its forward end with a head 2 which prothe body.

iects a considerable distance to one side of This head is provlded 1n its upper face, and adjacent to one side thereof,

with a groove 3 disposed parallel with body threaded into head 2.

which passes a securing screw 7 which is Plate 6 is provided tool 5.

a retaining plate 9 is secured to the side of head 2 and projects above the head adjacent to rib 8, this plate serving to prevent lateral displacement of the clamping plate.

means of plate 6 and screw 7 the tool 5 can be effectively gripped so as to prevent any displacement of the tool when in use, the boss 4 serving to brace the tool against downward pressure.

By having groove 3 parallel with body 1 the holder is adapted to receive tools of comparatively great length and can, therefore, accommodate varying lengths of tools.

What I claim is 1 A tool holder of the character described comprising a body portion, a head formed on one end of the body portion and being provided with a laterally offset longitudi nally disposed tool receiving groove, a boss formed on said head at the forward end thereof and providing a continuation for the bottom of the groove, a clamping plate adjustably secured to the head and being adapted to hold said tool operatively positioned in the groove and a substantially V- shaped rib depending from one end of the plate to provide a fulcrum upon which the plate rocks as and for the purpose specified.

In testimony whereof I my signature.

KARL STUDINKA.
